Working with the terminal using a command interface is very fast and effective way of doing stuff. But have you tried working with the terminal, listening to a music via headphones and having a terminal warning or tab-completion beep / bell turned ON at the same time? Well it can be very annoying. Listening to the PC Speaker beeps via headphones is very close to a feeling of hitting your head with a hammer. Even without headphones this beeping bell sound is very annoying.
-bash: /dev/null: Permission denied
Posting the Debian answer for posterity…
sudo su \
&& rm -rf /dev/null \
&& mknod /dev/null c 3 2 \
&& chmod 666 /dev/nullUnable to run vagrant up with ubuntu 18.04
Although you’ve got the errors you’re still able to connect to the machine:
vagrant ssh
and install the ifupdown package
apt-get install ifupdown
and reload the machine.

Restrict SSH user access to certain directory using chrooted jail on Debian 9

How to fix python SSL CERTIFICATE_VERIFY_FAILED
Here I explain how to fix Python SSL errors when trying to access DirectAdmin API using the https protocol in Python (e.g. by using the urllib, urllib2. httplib or requests). This error looks like:
raise ApiError("HTTP Error: %s" % e.reason)
directadmin.api.ApiError: HTTP Error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:661)
Server certificate verification by default has been introduced to Python recently in 2.7.9. This protects against man-in-the-middle attacks, and it makes the client sure that the server is indeed who it claims to be.
As a quick (and insecure) fix, you can turn certificate verification off, by:
1. Set PYTHONHTTPSVERIFY environment variable to 0. For example, run
export PYTHONHTTPSVERIFY=0 python your_script
or
PYTHONHTTPSVERIFY=0 python your_script
2. Alternatively, you can add this to your code before doing the https request
import os, ssl
if (not os.environ.get('PYTHONHTTPSVERIFY', '') and
getattr(ssl, '_create_unverified_context', None)):
ssl._create_default_https_context = ssl._create_unverified_context
